Description
The application is an original applying number 200310100413.9, and denomination of invention is divided an application for " AC type plasma display panel ".
Technical field
The present invention relates to a kind of AC type plasma display panel, particularly relate to a kind of AC type plasma display panel (AC plasma dispsaypanel is called for short AC PDP) that obtains higher brightness and discharging efficiency.
Background technology
The communication interface of flat-panel screens behaviour and information (information), flat-panel screens mainly contains following several at present: plasma scope, organic electro-luminescent display (Organic Electro-LuminescentDisplay, OELD), LCD (Liquid Crystal Display, LCD) and light-emitting diode (Light Emitting Diode, LED) etc.Wherein, plasma scope with its large scale, self-luminous, no visual angle is interdependent, frivolous and advantage such as full-colorization and have great application potential, is expected to become the main flow of follow-on flat-panel screens.
Plasma scope be a kind of utilize phosphor material (Phosphor) to be subjected to ultraviolet light (Ultraviolet light) irradiation after, the characteristic that can radiate visible light (Visible light) reaches the display module of display effect.Its ray structure is made of pair of electrodes, discharge gas and phosphor material layer.When the voltage between anode and negative electrode surpassed a critical value, discharge gas promptly can produce electric discharge phenomena and send ultraviolet light.The phosphor material layer promptly can enter excitation state (Excited state) after being subjected to UV-irradiation.Return in the process of ground state (Ground state) in phosphor material self-excitation attitude, the phosphor material layer can produce the visible light of different colours according to the characteristic of its different materials, and this is the principle of luminosity of plasma scope.
But use the characteristics of the mode of traditional R, G, the horizontal pixel of B (pixel) to be that R, G, single pixel of B (are picture element, this paper all is called pixel) be the inferior pixel design of sleeve configuration, its shortcoming has its difficulty for high the parsing in pixel that is the littler inferior pixel making, and if when using barrier rib (rib) to increase time pixel intensity, efficient and discharge stability, easier its discharge voltage (Vf) that causes improves, and the design of its sleeve configuration electrode more can cause and must use more that high voltage discharges, and it is higher that just it keeps voltage (Vs).And similar tradition is used for cathode ray tube (cathode ray tube, be called for short CRT) and inferior dot structure arranged of the triangle (delta configuration) of other display unit such as No. the 6373195th, United States Patent (USP) description, just can remedy this problem generation.

Therefore, characteristics of the present invention are to adopt the electrode of keeping of class palisade design, thus ultraviolet light can be excited uniformly the phosphorescent layer around it, and the path of ultraviolet light is shorter, can improve brightness and improve efficient.In addition, be example with Fig. 2 A, keep the 3rd long position 219 of line length in the electrode 216 and can improve discharge probability (probability), thus its discharge voltage (Vf) with keep voltage (Vs) and all can descend.And the present invention can make the large-size pixel design of delta arrangement, because of its phosphorescent layer obtains evenly efficient exciting, and then obtains higher brightness and efficient.
The above, it only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, though the present invention discloses as above with preferred embodiment, yet be not in order to limit the present invention, any those skilled in the art, in not breaking away from the technical solution of the present invention scope, when the technology contents that can utilize above-mentioned announcement is made a little change or is modified to the equivalent embodiment of equivalent variations, but every content that does not break away from technical solution of the present invention, according to technical spirit of the present invention to any simple modification that above embodiment did, equivalent variations and modification all still belong in the scope of technical solution of the present invention.
